ICE CONCRETE
A FINNISH INVENTION Ice concrete is the name of a new, porous, astonishingly light building material invented in Finland. Like ordinary concrete, it is composed of cement and sand. Crushed ice or snow is used during the process of mixing. Heat evaporates the water of the melting ice, and the result is a block or brick, uniformly honeycombed with minute pores. The number of pores varies directly with the quantity of ice or snow mixed with tho cement and sand. Building blocks thus made are exceedingly light and durable. In a house or office building of ice concrete there is a saving of weight varying from 20 to 50 per "cent. Because they arc cellular in structure the blocks act ns insulators to keep out heat in summer and cold in winter. If the concrete is made without sand, the resultant product is a tough compound that can bo sawn, nailed, screwed, chiselled, and cut as readily as if it were wood.
